Highly efficient Barbier allylation from allyl alcohol using iridium(I)/tin(II): Unusual and indirect roles of allyl alcohol and tin
A reagent combination of SnCl2 and catalytic [Ir(COD)Cl](2) (1 mol%) in THF-H2O promotes the reaction of allyl alcohol and aldehyde leading to homoallyl alcohols in good to excellent yields. Control studies suggest the plausible participation of pi-allyl-iridium intermediate(s) from which direct allyl transfer takes place to aldehyde. (c) 2005 Elsevier B.V. All rights reserved.
